Description

Technical Field

[0001] This invention relates to a pipeline, and more specifically, to a municipal pipeline. Background Technology

[0002] Municipal pipelines, as a core component of urban underground integrated pipeline systems, integrate multiple functions such as water supply, drainage, gas transmission, heat supply, power transmission and communication support. They are an indispensable key infrastructure for maintaining the normal operation of the city and the daily life of residents.

[0003] In municipal pipeline systems, drainage pipes bear the crucial responsibility of draining water from roads. To ensure smooth drainage, filter plates are typically installed inside the drainage pipes. These filter plates, through their physical barrier function, effectively intercept various debris such as solid particles, suspended solids, and fibers in sewage, preventing them from entering subsequent pipes or treatment equipment, thereby avoiding pipe blockage and equipment wear.

[0004] However, when the filter plate becomes clogged, its cross-sectional area for water flow shrinks significantly, slowing down the water flow and affecting drainage capacity. Taking the filter plate at the inlet of a municipal drainage pipe as an example, if it becomes clogged during heavy rain, surface water will not be able to drain in time, potentially causing urban flooding.

[0005] To address this challenge, a patent for invention entitled "Municipal Pipeline with Debris Retrieval in Municipal Control System" (Publication No.: CN118601119B) has been disclosed in the existing technology. This patent designs a liftable retrieval plate that can automatically and quickly retrieve debris from inside the pipe according to the amount of debris, thereby significantly improving retrieval efficiency.

[0006] Nevertheless, the structure still has certain drawbacks: when too much debris accumulates on the retrieval platform and is not cleared in time, it also faces the risk of flooding. Especially during heavy rain, timely retrieval operations become extremely difficult. Therefore, further improvements and optimizations to the structure are necessary. Summary of the Invention

Guide posts are provided at both ends of the filter plate. The guide posts are arranged in a racetrack shape and are rotatably connected to the connecting seat through the guide posts. The vertical pipe is provided with a guide groove and a rotating cavity on its wall. The lower end of the guide groove is connected to the rotating cavity. The guide column is slidably arranged along the guide groove. When the impurities on the filter plate gradually increase, the guide column gradually moves along the guide groove into the rotating cavity, and the guide column drives the filter plate to rotate 90°. The control component includes an adjusting member and a lifting member, the adjusting member being used to rotate the filter plate in the rotating chamber by 90°. The rising element is used to drive the filter plate to move up to the upper end of the vertical tube.

[0009] The present invention is further configured such that: each of the filter plates is provided with a plurality of filter holes, and the filter plates are provided with at least two sets, and are arranged from top to bottom as a first plate body and a second plate body along the height direction of the vertical pipe, wherein the diameter of the filter holes on the first plate body is greater than the diameter of the filter holes on the second plate body.

[0010] The present invention is further configured such that: the guide posts are disposed at both ends of the filter plate in the first direction, and guide arc blocks are disposed on both sides of the filter plate in the second direction, wherein the first direction and the second direction are perpendicular to each other.

[0011] The present invention is further configured such that: a guide portion is provided at the connection between the rotating cavity and the guide groove, and a guide block is provided on the guide post; when the guide block moves along the guide portion, the filter plate rotates accordingly.

[0012] The present invention is further configured such that: the limiting member includes a pressure limiting plate and a limiting spring located inside the tube, the pressure limiting plate is laterally slidably connected to the guide groove through the limiting spring, and the upper end face and the lower end face of the pressure limiting plate are both provided with pushing inclined surfaces.

[0013] The present invention is further configured such that: a pressure sensor is provided inside the rotating cavity, and the pressure sensor is triggered when the guide column moves into the rotating cavity; The pressure sensor is connected to an external controller.

[0014] The present invention is further configured such that: the sealing assembly includes a sealing motor, a sealing plate, and a sealing collar, the sealing collar being sleeved on the outer ring of the sealing plate, the sealing plate being rotatably connected to the pipe body and connected to the sealing motor, and the sealing motor being connected to a controller.

[0015] The present invention is further configured such that: the adjusting member includes a first adjusting rod, a second adjusting rod, and a linkage rod, the first adjusting rod and the second adjusting rod are both threadedly connected to the tube body, and the lower end of the first adjusting rod can move and extend into the rotating cavity; The lower end of the second adjusting rod is linked to the linkage rod, and the linkage rod and the first adjusting rod are respectively located on both sides of the guide post; The linkage includes a deflector rod and an upper push rod, with the two ends of the deflector rod respectively linked to the upper push rod and the second adjusting rod.

[0018] In summary, the present invention has the following beneficial effects: it utilizes multiple sets of filter components to perform multi-stage and multi-layer filtration operations. During the filtration process, impurities will accumulate sequentially on the filter plate. When there are too many impurities at the top of the filter plate, the water pressure will gradually increase, thereby pushing the filter plate downward. When the filter plate moves into the rotating cavity, the filter plate can rotate 90°. At this time, the plane of the guide column abuts against the bottom surface of the rotating cavity, which can maintain the stability of the filter plate and ensure that the water flow can flow downward from both sides.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 5 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a municipal pipeline, including a pipe body 1, a filter assembly 2, a sealing assembly 3 and a control assembly 4, wherein the pipe body 1 includes at least a section of vertical pipe located at the water inlet end, and the filter assembly 2 is provided in multiple sets and arranged along the length direction of the vertical pipe. The sealing component 3 is installed at the outlet end of the pipe body 1 to cut off the passage of the pipe body 1; The filter assembly 2 includes a limiting member 21, a connecting seat 22, and a filter plate 23. Two sets of limiting members 21 are provided and are symmetrically arranged on both sides of the vertical pipe. Two sets of connecting seats 22 are provided. Both ends of the filter plate 23 are provided with guide posts 24. The guide posts 24 are arranged in a racetrack shape and are rotatably connected to the connecting seat 22 through the guide posts 24. The vertical pipe has a guide groove 11 and a rotating cavity 12 on its wall. The lower end of the guide groove 11 is connected to the rotating cavity 12. The guide post 24 slides along the guide groove 11. Figure 5 and Figure 2 As shown, the size of the guide groove 11 is adapted to the size of the guide post 24, and can only support the guide post 24 to slide up and down in the guide groove 11. The size of the rotating cavity 12 is larger than the size of the guide groove 11, so when the guide post 24 is in the rotating cavity 12, it can be rotated.

[0023] The connector 22 is slidably connected to the tube body 1.

[0024] like Figure 1 As shown, the guide grooves 11 in the filter components 2 of different groups are misaligned.

[0025] As impurities on the filter plate 23 gradually increase, the guide column 24 gradually moves along the guide groove 11 into the rotating cavity 12, and the guide column 24 drives the filter plate 23 to rotate 90°. The control assembly 4 includes an adjusting member 41 and an lifting member 42. The adjusting member 41 is used to rotate the filter plate 23 in the rotating chamber 12 by 90°. The rising component 42 is used to drive the filter plate 23 to move upward to the upper end of the vertical tube.

[0026] The design of this invention utilizes multiple sets of filter components 2 to perform multi-stage and multi-layer filtration operations. During the filtration process, impurities will accumulate sequentially on the filter plate 23. When there are too many impurities at the top of the filter plate 23, the water pressure will gradually increase, thereby pushing the filter plate 23 to move downward. When the filter plate 23 moves into the rotating cavity 12, the filter plate 23 can rotate 90°. At this time, the plane of the guide column 24 abuts against the bottom surface of the rotating cavity 12, which can maintain the stability of the filter plate 23 and ensure that the water flow can flow downward from both sides.

[0027] The present invention is further configured such that: each filter plate 23 is provided with a plurality of filter holes, and the filter plate 23 is provided with at least two sets, and is arranged from top to bottom as a first plate body and a second plate body along the height direction of the vertical pipe, wherein the diameter of the filter holes on the first plate body is greater than the diameter of the filter holes on the second plate body.

[0028] This structure is designed to perform multi-stage filtration. When the filter plate 23 is flipped, the upper filter plate 23 will also flip, while the lower filter plate 23 can still perform filtration. Compared with existing technologies, this structure can be used for a longer period of time.

[0029] The present invention is further configured such that: guide posts 24 are disposed at both ends of filter plate 23 in the first direction, and guide arc blocks 25 are disposed on both sides of filter plate 23 in the second direction, with the first direction and the second direction being perpendicular to each other.

[0030] like Figure 2 As shown, the design of the guide arc block 25 ensures that regardless of whether the filter plate 23 rotates 90° to the left or right, the guide arc block 25 on the filter plate 23 always faces upward. At this time, the water flow will flow from top to bottom along the guide arc block 25 to both sides, and will not wash the filter surface of the filter plate 23. This minimizes the amount of filter residue remaining on the filter plate 23, reduces the impact of filter residue on the upper filter plate 23 on the lower filter plate 23, and maintains the filtration effect of the lower filter plate 23.

[0031] The present invention is further configured such that: a guide portion 13 is provided at the connection between the rotating cavity 12 and the guide groove 11, and a guide block 241 is provided on the guide post 24; when the guide block 241 moves along the guide portion 13, the filter plate 23 rotates accordingly.

[0032] Combination Figure 5 and Figure 3 as well as Figure 4 As shown: In this structure, when the filter plate 23 moves from top to bottom, the guide block 241 will abut against the guide part 13, thereby causing the filter plate 23 to deflect to one side. At this time, under the impact of the water flow, the filter plate 23 rotates 90°, changing from a horizontal state to a vertical state.

[0033] The design of the guide section 13 prevents the filter plate 23 from moving vertically downwards, causing it to become horizontally stuck in the pipe, thus affecting the rotation and water flow of the filter plate 23.

[0034] The present invention is further configured such that: the limiting member 21 includes a pressure limiting plate 5 and a limiting spring 51 located inside the tube body 1, the pressure limiting plate 5 is laterally slidably connected to the guide groove 11 through the limiting spring 51, and the upper end surface and the lower end surface of the pressure limiting plate 5 are both provided with a pushing inclined surface 52.

[0035] like Figure 3 As shown, when the water pressure and weight at the upper end of the filter plate 23 gradually increase, the guide column 24 can push the pressure limiting plate 5 to move, thereby releasing the limiting effect of the moving member 21.

[0036] Since the inclined plane 52 is located on the upper and lower sides of the pressure limiting plate 5, when the upper filter plate 23 moves up or down, the limiting member 21 can be displaced by pushing the inclined plane 52.

[0037] The present invention is further configured such that: a pressure sensor is provided inside the rotating cavity 12, and the pressure sensor is triggered when the guide column 24 moves into the rotating cavity 12; The pressure sensor is connected to an external controller.

[0038] The controller and pressure sensor are designed so that when a filter plate 23 moves down, the guide post 24 can abut against the pressure sensor, causing the controller to receive a trigger signal. Based on the received signal, the current status of the filter assembly 2 in the pipeline can be determined. Therefore, after heavy rain, it is possible to determine which part of the pipeline needs to be salvaged and cleaned.

[0039] The present invention is further configured such that: the sealing component 3 includes a sealing motor 31, a sealing plate 32, and a sealing ring 33, the sealing ring 33 is sleeved on the outer ring of the sealing plate 32, the sealing plate 32 is rotatably connected to the pipe body 1 and is connected to the sealing motor 31, and the sealing motor 31 is connected to the controller.

[0040] The design of this structure allows the controller to remotely control the opening and closing of the sealing motor 31. When the sealing motor 31 is started, it can control the rotation of the sealing plate 32, thereby cutting off the flow of the pipe body 1 under the action of the sealing ring 33 and the sealing plate 32. Then, the required retrieval equipment is used for retrieval operations.

[0041] The present invention is further configured such that: the adjusting member 41 includes a first adjusting rod 411, a second adjusting rod 412, and a linkage rod 413, the first adjusting rod 411 and the second adjusting rod 412 are both threadedly connected to the tube body 1, and the lower end of the first adjusting rod 411 can move and extend into the rotating cavity 12; The lower end of the second adjusting rod 412 is linked to the linkage rod 413, and the linkage rod 413 and the first adjusting rod 411 are located on both sides of the guide post 24 respectively; The linkage 413 includes a deflector rod and an upper push rod, with both ends of the deflector rod being linked to the upper push rod and the second adjusting rod 412, respectively.

[0042] Note that the deflector and push rod are connected to the tube 1 via a spring-loaded sliding connection.

[0043] like Figure 3 As shown, the design of this structure requires the filter plate 23 to be changed from a vertical state back to a horizontal state when the salvage operation is required. Therefore, the first adjusting rod 411 is rotated first so that the lower end of the first adjusting rod 411 is located above the right side of the guide post 24. Then, the second adjusting rod 412 is rotated, causing the second adjusting rod 412 to move downward, which in turn pushes the deflector rod to the right and the upper push rod to move upward, thereby causing the guide column 24 to rotate clockwise.

[0044] During clockwise rotation, the guide post 24 will come into contact with the first adjusting rod 411, thus ensuring that the guide post 24 does not move vertically upward, but can rotate.

[0045] The present invention is further configured such that: the rising member 42 includes a water inlet pipe 421 and a booster pump 422, one end of the water inlet pipe 421 is located at the upper end of the pipe body 1, and the other end is connected to the inside of the pipe body 1, the booster pump 422 is connected to the controller, and a sealing sleeve 423 is screwed to the upper end of the water inlet pipe 421.

[0046] The design of the booster pump 422 and the inlet pipe 421 allows for the following: when all the required filter plates 23 are in a horizontal position, the sealing sleeve 423 is opened, and the water hose for retrieving the vehicle is inserted into the inlet pipe 421. Under the action of the booster pump, water is poured into the pipe body 1. At this time, the sealing plate 32 at the outlet end of the pipe body 1 is cut off. The water pressure at the bottom of the pipe body 1 increases, and the buoyancy of the water moves the filter plates 23 upward to the inlet end of the pipe body 1. Then, the filter plates 23 are removed one by one, and new filter plates 23 are installed on the guide column 24. The removed filter plates 23 can be transported to a dedicated cleaning area for cleaning operations.

[0047] The present invention is further configured such that the guide arc block 25 is made of airbag material.

[0048] Since the guide arc block 25 is made of airbag material, the filter plate 23 can increase the buoyancy of the water on the filter plate 23 during the reverse water injection process inside the pipe body 1, so that the filter plate 23 can move upward more stably.

[0049] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
